Rotating spindle box for conical part machining

Abstract

The invention relates to a rotating spindle box for conical part machining in the technical field of lathe machining. The rotating spindle box comprises a base and a rotating box body, an input shaft is arranged on the left vertical face of the base and drives a transverse shaft through a gear, a bevel gear is arranged at the right end of the transverse shaft, an output shaft is arranged on the right vertical face of the rotating box body, and a bevel gear is arranged at the left end of the output shaft. A vertical shaft is mounted in the middle of the base, the upper portion of the vertical shaft enters the rotating box body, a bevel gear at the upper end of the vertical shaft is matched with the bevel gear at the left end of the output shaft, and a bevel gear at the lower end of the vertical shaft is matched with the bevel gear at the right end of the transverse shaft; a worm and a worm gear are arranged below the base, the worm drives the worm gear to drive a worm gear shaft to rotate, the upper end of the worm gear shaft drives a turntable through gear transmission, and the turntable drives the rotating box body and the output shaft to rotate around the vertical shaft; as long as the worm is rotated, the included angle between the output shaft and the center line of a lathe spindle can be easily adjusted, conical parts are smoothly machined, and the worm and the worm gear are used, transmission is stable, and fine machining is achieved; and transmission and angle adjustment are integrated, and practicability is high.

Description

technical field [0001] The invention relates to the field of lathe processing fixture technology and equipment, in particular to a rotating headstock for processing conical parts. Background technique [0002] In the mechanical processing industry, lathes are the most widely used processing tools. At present, the processing of conical inner and outer circles and conical threads on ordinary lathes is done by manually controlling the handwheel of the machine tool. The processing process is complicated and cumbersome. Precision control is also relatively difficult. It takes a long time to process parts and requires high technical requirements for operators. If you are not careful, it is easy to process substandard products or even a large number of waste products. [0003] Ordinary lathes process conical workpieces, such as cones, inner tapered holes, tapered threads, etc., generally using one of the following processes: [0004] 1. Rotating small tool holder method: This proc...

Problems solved by technology

During processing, only manual feeding is required, the labor intensity of the operator is high, and the surface quality of the workpiece is not easy to guarantee

In addition, due to the limitation of the stroke of the small slide after swinging, only workpieces with short tapered surfaces can be processed;

[0005] 2. Tailstock offset method: workpieces with large angles cannot be processed, and inner tapered holes cannot be processed;

[0007] 4. Bed head offset method: This process needs to adjust the head of the lathe, the process is complicated, and it is rarely used;

[0008] Although ordinary lathes can process conical workpieces, the above-mentioned methods all have greater processing difficulty or more complicated mold making.
